Description
Technical field
The application relates at single cylinder knocking control period for improving the system and method for part temperatures protection.
Background technique
The ignition timing of explosive motor can change to provide optimal engine to operate according to engine operating condition.As an example, in order to increase engine efficiency and reduce fuel consumption, the spark timing of each cylinder can be positioned in Maximum Torque minimum ignition advance angle (MBT) place.In response to abnormal combustion event (as caused due to pinking), so ignition timing can be delayed by from optimum timing.The people such as Haraldson are a kind of exemplary method shown in WO 2011023852.Wherein, the knock control between cylinder and cylinder is performed by the pinking controlled in each cylinder via the independence adjustment of the spark timing to each cylinder.
But the present inventor has realized that at this potential problems utilizing this kind of method.Although the knock control between cylinder and cylinder allows to solve pinking more reliably, the delivery temperature of each cylinder can to use from respective group and (as in V-motor) between the groups other cylinders spark lag (or in advance) and change significantly.When operating close to parts temperature limit (temperature limits as exhaust catalyst, exhaust steam turbine entrance, one or more exhaust valves etc.), if one or more cylinder has the spark postponed from the reference value of spark, the delivery temperature in those cylinders can exceed limiting design value.Therefore, this can reduce motor life-span and increase parts replace needs.Part temperatures can be run through the fuel area density of whole cylinders of whole group (such as, in I-motor) or two groups (such as, in V-motor) by increase/reduction and be controlled.Such as, the fueling of whole cylinders of motor can be adjusted the change of the delivery temperature predicting each cylinder further based on the overall engine temperature model using the global regulation device (modifier) of spark and igniter (lambse) to know by inference.But this can cause excessive waste of fuel and the fuel economy of overall reduction and engine performance.
Summary of the invention
In one example, some the problems referred to above can be solved by the method for motor, the method guarantee single cylinder knocking control and maintaining member temperature in the limit value of waste of fuel with reduction.A kind of exemplary method comprises: maintain in threshold value via each in spark adjustment and fueling adjustment by engine exhaust temperature, the adjustment of this spark is based on the self adaption knock control value of each in multiple engine cylinder, and the adjustment of this fueling adjusts based on spark.
Such as, drive circulation in more, based on the pinking generation event in each cylinder, learn separately the self adaption knock value of each cylinder.Based on the self adaption knock value of each cylinder, each cylinder can use the different spark lag amount started from MBT to operate.Such as, the cylinder with higher tendency to detonate can have higher pinking adaptation value and the spark timing of the further delay started from MBT can be used to operate, and the cylinder with lower tendency to detonate can have lower pinking adaptation value and the spark timing of the less delayed started from MBT (such as, when spark lag, when there is spark at MBT place or from MBT when spark in advance) can be used to operate.Then cylinder fueling between group and group can be controlled by the delivery temperature adjusting to enable particular group based on the spark adjustment of learning.Particularly, for each group, the cylinder with maximum spark retardation can be determined.Then can be adjusted the delivery temperature of given group is maintained under threshold value based on maximum spark retardation the fueling of whole cylinders of that group.As an example, whole cylinders of this group can based on maximum spark retardation by enrichment.Similarly, the spark of the cylinder of another cluster engine (as in V-motor) can be adjusted based on respective adaptation value, and adjusts fueling based on the cylinder with maximum spark retardation.Alternatively, the cylinder with maximum spark retardation can based on maximum spark retardation by fueling to guarantee having delivery temperature to be controlled, and can be adjusted based on the fueling determined the fueling of another residue cylinder of given group the exhaust air-fuel ratio of given group is maintained stoichiometric proportion place or near stoichiometric proportion or air-fuel ratio (Maximum Torque (LBT) as the pedal performance-the rarest of Full-open) any reference (base) of ordering.
In this way, the knock control between cylinder from cylinder can be implemented and cause compensating the thermogenetic difference of exhaust due to the spark adjustment of different cylinders.Adjust cylinder fueling by the spark governor of the cylinder based on worst case, can provide due to spark adjustment and the delivery temperature that causes rises predicts more accurately.By based on have maximum spark retardation cylinder (cylinder of worst case) spark governor and to whole cylinder fuelings of cluster engine, can guarantee that any cylinder or group can not exceed the temperature limit of engine components preferably.Therefore, improve delivery temperature to control.By calculating the fuel quantity had to be added to each cluster engine based on the fuel trimmer adjusted delivery temperature, temperature and knock control can be implemented when not wasting fuel.Therefore, entire engine fuel economy and engine performance is which improved.
Should be appreciated that and provide foregoing invention content to introduce some concepts in simplified form, these concepts will be further described in a specific embodiment.This does not also mean that the key or essential characteristic of determining theme required for protection, and the scope of theme required for protection is limited uniquely by the claim after following embodiment closely.In addition, theme required for protection is not limited to the mode of execution solving any shortcoming mentioned above or in any part of the present disclosure.

Fig. 1 shows the firing chamber of explosive motor 10 or the example embodiment of cylinder.Motor 10 can receive from the controling parameters of the control system comprising controller 12 with via the input of input device 132 from vehicle operator 130.In this example, input device 132 comprises accelerator pedal and the pedal position sensor 134 for generation of proportional pedal position signal PP.The cylinder of motor 10 (herein also referred to as " firing chamber ") 14 can comprise and has piston 138 and be positioned at chamber wall 136 wherein.Piston 138 can be coupled to bent axle 140, makes the to-and-fro motion of piston be converted into the rotary motion of bent axle.Bent axle 140 can be coupled at least one driving wheel of passenger vehicle via transmission system.Further, starter motor can be coupled to bent axle 140 to guarantee the start-up operation of motor 10 via flywheel.
Cylinder 14 can receive inlet air via a series of inlet air passage 142,144 and 146.Inlet air passage 146 can be communicated with other cylinders of the motor 10 except cylinder 14.In certain embodiments, one or more gas-entered passageway can comprise increasing apparatus (as turbosupercharger or mechanical supercharger).Such as, Fig. 1 illustrates the motor 10 of the turbosupercharger of the compressor 174 being configured with and being included in and arranging between gas-entered passageway 142 and 144 and the exhaust steam turbine 176 arranged along exhaust passage 148.Compressor 174 can via axle 180 at least in part by exhaust steam turbine 176 energy supply, and wherein increasing apparatus is configured to turbosupercharger.But provide in other examples of mechanical supercharger at such as motor 10, exhaust steam turbine 176 can optionally be omitted, wherein compressor 174 can carry out energy supply by the machinery input from motor or motor.The closure 20 comprising Rectifier plate 164 can be provided along the gas-entered passageway of motor, for changing flow rate and/or the pressure of the inlet air being provided to engine cylinder.Such as, closure 20 can be disposed in the downstream of the compressor 174 shown in Fig. 1 or alternatively may be provided in the upstream of compressor 174.
Exhaust passage 148 can receive exhaust from other cylinders of the motor 10 except cylinder 14.Exhaust sensor 128 is illustrated the exhaust passage 148 being couple to emission control system 178 upstream.Sensor 128 can be selected from for providing the various suitable sensor of the instruction of exhaust air/fuel ratio, such as, various suitable sensors such as linear oxygen sensors or UEGO (general or wide area exhaust oxygen), bifurcation lambda sensor or EGO (as shown), HEGO (EGO of heating), NOx, HC or CO sensor.Emission control system 178 can be three-way catalyst (TWC), NOx trap, other emission control system various or their combination.
Delivery temperature can be estimated by the one or more temperature transducer (not shown) be positioned in exhaust passage 148.Alternatively, delivery temperature can be known by inference based on engine operating condition (as rotating speed, load, air-fuel ratio (AFR), spark lag etc.).Further, delivery temperature can be calculated by one or more exhaust sensor 128.Will be appreciated that, delivery temperature can be estimated alternatively by the combination in any of the temperature estimation method listed herein.
Each cylinder of motor 10 can comprise one or more intake valve and one or more exhaust valve.Such as, cylinder 14 is illustrated at least one air inlet comprising the upper area being positioned at cylinder 14 and promotes valve 150 and at least one exhaust lifting valve 156.In certain embodiments, each cylinder (comprising cylinder 14) of motor 10 can comprise at least two air inlets lifting valves and at least two exhaust lifting valves of the upper area being positioned at cylinder.
Intake valve 150 can be controlled by controller 12 by cam-actuated via cam-actuated system 151.Similarly, exhaust valve 156 can be controlled by controller 12 via cam-actuated system 153.Eachly in cam-actuated system 151 and 153 can comprise one or more cam and cam profile conversion (CPS), variable cam timing (VCT, one or more to change air door operation as shown in Figure 1), in Variable Valve Time (VVT) and/or lift range variable (VVL) system that can be operated by controller 12 can be utilized.The position of intake valve 150 and exhaust valve 156 can be determined by valve position sensor 155 and 157 respectively.In alternate embodiments, intake valve and/or exhaust valve can be activated by electric air valve and control.Such as, cylinder 14 can alternatively comprise via the intake valve of electric air valve actuator control with via the exhaust valve of cam-actuated control comprising CPS and/or VCT system.In further embodiments, intake valve and exhaust valve can be controlled by the valve actuator commonly used or actuating system or Variable Valve Time actuator or actuating system.
Cylinder 14 can have compression ratio, and it is the volume when piston 138 is in lower dead center and the ratio of volume during at top dead center.Usually, compression ratio is in the scope of 9:1 to 10:1.But in some examples using different fuel, compression ratio can increase.Such as, when the fuel or use that use higher octane have the fuel of higher potential enthalpy of vaporization, this may occur.Directly spray if used, because it is on the impact of engine knock, compression ratio also can increase.
In certain embodiments, each cylinder of motor 10 can comprise the spark plug 192 for taking fire.Under the operator scheme selected, in response to the spark advance signal SA carrying out self-controller 12, ignition system 190 can provide ignition spark to firing chamber 14 via spark plug 192.But in certain embodiments, spark plug 192 can be omitted, as the situation that motor 10 can be passed through automatic ignition or be burnt by the injection beginning of fuel, as the situation that can utilize some diesel engine.
In certain embodiments, each cylinder of motor 10 can be configured with the one or more fuel injectors providing fuel to it.As a non-limiting example, cylinder 14 is illustrated and comprises a fuel injector 166.Fuel injector 166 is illustrated and is directly coupled to cylinder 14, for proportional the directing injection of fuel into wherein of pulse width FPW with the signal received from controller 12 via electronic driver 168.In this way.Fuel injector 166 provides the direct injection (hereafter also referred to as " DI ") of the fuel being called as combustion cylinder 14.Although Fig. 1 illustrates that sparger 166 is for side spray emitter, it also can be positioned at the top of piston, as the position near spark plug 192.Due to the lower volatility of some ol-yl fuel, when using ol-yl fuel handling motor, mixing and burning can be improved in such position.Alternatively, sparger can be positioned at intake valve top and near intake valve to improve mixing.Fuel can be transported to fuel injector 166 from the high-pressure fuel system 8 comprising fuel tank, petrolift and fuel rail.Alternatively, fuel can be carried by single-stage petrolift at lower pressures, and in this case, the timing that direct fuel sprays can be more restricted than using high-pressure fuel system during compression stroke.Further, although not shown fuel tank, it can have pressure transducer signal being provided to controller 12.Will be appreciated that, in alternate embodiments, sparger 166 can be the passage injector of intake duct fuel being provided to cylinder 14 upstream.
Although it should also be appreciated that the embodiment illustrated describes motor by being operated via single direct sparger burner oil; But in alternate embodiments, motor can be operated from the relative emitted dose of often kind of sparger with change by use two kinds of spargers (such as, direct sparger and passage injector).
Fuel can during the simple subprogram of cylinder by injector conveying to cylinder.Further, can change with operating mode from the distribution of the fuel of injector conveying and/or relative quantity.In addition, for single combustion incident, the multi-injection of the fuel of conveying can circulate at every turn be performed.Multi-injection can be performed at compression stroke, aspirating stroke or their any suitable Assemble Duration.In addition, fuel can be injected with the fuel ratio (AFR) of the air and injection that adjust burning in cycle period.Such as, fuel can be injected to provide stoichiometric AFR.AFR sensor can be included to the estimated value providing AFR in cylinder.In one example, AFR sensor can be exhaust sensor (as EGO sensor 128).By measuring the remaining oxygen amount (for lean mixture) in being vented or unburned hydrocarbon amount (for rich mixture), sensor can determine AFR.Therefore, AFR may be provided in Lambda (λ) value, namely for the AFR of given mixture reality and the ratio of stoichiometric proportion.Therefore, λ is the mixture of 1.0 instruction stoichiometric proportions, can have the λ value being less than 1.0, and the mixture rarer than stoichiometric proportion can have the λ value being greater than 1 than the mixture of stoichiometric proportion richness.
As mentioned above, Fig. 1 illustrates an only cylinder of multicylinder engine.Therefore, each cylinder can comprise its one group of air inlet/exhaust valve, (one or more) fuel injector, spark plug etc. similarly.
Fuel tank in fuel system 8 can accommodate the fuel with different fuel performances (propellant compositions as different).These differences can comprise different alcohol content, different octane values, different vaporization heat, different fuel mix and/or their combination etc.
Motor 10 may further include the detonation sensor 90 being couple to each cylinder 14, for determining abnormal combusted cylinder event.In alternate embodiments, one or more detonation sensor 90 can be coupled to the position of the selection of engine block.The ion transducer that detonation sensor can be accelerometer on cylinder block or be configured in the spark plug of each cylinder.The output of detonation sensor can be combined with the abnormal combustion event indicated in cylinder with the output of bent axle acceleration sensor, such as, to determine that the pinking in one or more cylinder occurs.As an example, pinking can be instructed in response to the knock sensor signal produced in the window occurred after cylinder spark event.In addition, pinking can exceed threshold frequency higher than threshold value and be instructed in response to detonation sensor output signal strength.
In response to the instruction of pinking, can implement to slow down action.Such as, pinking can use spark lag and/or EGR to solve.Such as, along with knock intensity increases, spark timing can be delayed by from MBT.In addition, the tendency to detonate of each cylinder can be learned and for upgrading self adaption knock value table, as Fig. 2 describe in detail.The frequency occurred along with the pinking in cylinder increases, and the self adaption knock control value of cylinder can increase.Further, along with the self adaption knock value of cylinder increases, the adjustment of the spark of cylinder can comprise and starts to postpone spark timing further from MBT.Then the self adaption knock value learned during cycle of engine (or vehicle driving cycle) and relevant spark multiplier may be used for during cycle of engine (or vehicle driving cycle) subsequently as the spark timing in the part adjustment cylinder of feedforward knock control (before the generation of pinking event).
Therefore, the self adaption knock value of each cylinder is learned independently, and each cylinder uses the different spark lag amounts from MBT to operate.That is, uneven spark lag may be there is between cylinders.Because spark lag amount affects in cylinder the amount producing exhaust heat, uneven spark lag can cause some cylinder (as have higher tendency to detonate and therefore have those cylinders of higher spark lag) to produce the heat more than other cylinders.In order to allow the exhaust heat temperature in motor or cluster engine to be maintained in part design limit value, the fueling to whole cylinders of motor or cluster engine can be adjusted based on the cylinder with maximum spark retardation, as Fig. 2 describe in detail.That is, based on the cylinder of " worst case ".Particularly, the exhaust heat temperature be associated with the maximum spark retardation in the cylinder with maximum self adaption knock value rises can be predicted.Fueling adjustment (such as, enrichment) then can rise based on the temperature of prediction and be determined, the delivery temperature organized can be maintained under threshold temperature.Whole cylinders of given cluster engine then can utilize the maximum spark retardation of the cylinder based on worst case common enrichment and similarly by fueling.
Be back to Fig. 1; controller 12 is illustrated as microcomputer, comprises microprocessor unit (CPU) 106, input/output end port (I/O) 108, in this particular example, is illustrated as ROM chip (ROM) 110 for the electronic storage medium of executable program and calibration value, random access memory (RAM) 112, keep-alive storage (KAM) 114 and data/address bus.Controller 12 can receive the various signals from the sensor being couple to motor 10, except those signals previously discussed, also comprises: from the measured value of the introducing Mass Air Flow (MAF) of mass air flow sensor 122; From the engine coolant temperature (ECT) of temperature transducer 116 being couple to cooling collar 118; From the PIP Profile Igntion PickUp signal (PIP) of hall effect sensor 120 (or other type) being couple to bent axle 140; From the throttle position (TP) of throttle position sensor; Carry out the manifold absolute pressure signal (MAP) of sensor 124; Cylinder AFR from EGO sensor 128 and the abnormal combustion from detonation sensor 90 and bent axle acceleration sensor.Engine rotational speed signal RPM can be produced by controller 12 according to signal PIP.Manifold pressure signal MAP from manifold pressure sensor may be used for providing the instruction of vacuum in intake manifold or pressure.
Storage medium ROM (read-only memory) 110 can utilize and represent and programmed by the mechanized data of the executable instruction of processor 106, for perform method described below and expectation but the various variants do not listed particularly.Example procedure is with reference to figure 2.
In this way, the system of Fig. 1 realizes the method maintained by engine exhaust temperature in threshold value via each in spark adjustment and fueling adjustment, wherein spark adjustment is based on the self adaption knock control value of each in multiple engine cylinder, and fueling adjustment adjusts based on spark.The spark ignition timing differently postponed in multiple engine cylinder by the self adaption knock control value based on respective cylinder, and then based on have in multiple cylinder maximum spark retardation only one ignition timing and adjust each in multiple cylinder fuel spray, delivery temperature can be maintained under threshold temperature.
Now go to Fig. 2, example procedure 200 be illustrated each cylinder differently adjusting motor spark governor and usually based on the cylinder of worst case spark governor and adjust the fuel trimmer of whole cylinders of motor.
At 202 places, this program comprises to be estimated and/or measures engine operating condition.These can comprise, such as, and engine speed, operator torque demand, engine temperature, delivery temperature, boosting, environmental condition etc.At 204 places, at least can determine that pinking may occur in engine cylinder based on the operating mode estimated.Such as, engine cylinder can have higher tendency to detonate under higher engine speed conditions.Therefore, the possibility of the pinking of each cylinder of motor can be individually evaluated.The possibility of pinking can depend on the single pinking history of each cylinder further.Such as, under a given set condition, some cylinders can have higher tendency to detonate.
If pinking is not expected, at 216 places, this program is used in the ignition spark timing at MBT place to operate engine cylinder.Alternatively, spark timing can be adjusted to based on the operating mode of the estimation except tendency to detonate and parameter and be delayed or early by from MBT.At 218 places, this program comprises the fueling of adjustment engine cylinder so that stoichiometrically than the burning air-fuel ratio operation near place or stoichiometric proportion.Alternatively, fueling can be adjusted to richer than stoichiometric proportion based on the operating mode of the estimation except tendency to detonate and parameter.
At 220 places, can determine whether pinking event occurs.Such as, even if the feedforward of pinking may do not had to indicate, feedback pinking can be instructed to based on the output of cylinder knocking sensor.If pinking is not instructed to, ignition timing can be maintained (such as, at MBT place) and this program can terminate.If feedback pinking is instructed to, at 222 places, the spark timing of the cylinder affected by pinking can be delayed by (such as, from MBT).In addition, the self adaption knock value of respective cylinder can be updated.
Be back to 204, if pinking is expected, at 206 places, this program comprises the self adaption knock control value based on each cylinder and determines spark governor or the adjustment of each cylinder of motor (or pinking be expected cluster engine).Cylinder and casing base can determine spark adjustment.Self adaption knock control value can be retrieved by the look-up table from the storage being stored in engine controller.This table can have the self adaption knock control value stored for each engine cylinder according to concrete operating mode (as engine speed and load state).Self adaption knock control value can be learned in advance during multiple cylinder operations driven in circulation.The self adaption knock control value of each cylinder can based on the pinking history of cylinder, and self adaption knock control value increases along with the increase of the frequency of pinking generation in cylinder.Then the spark governor of cylinder can be adjusted based on self adaption knock control value, and wherein along with the self adaption knock control value of cylinder increases, the spark timing in cylinder starts further delay from MBT.Therefore, based on the self adaption knock control value of each cylinder, each cylinder can use different or uneven spark lag amount to operate.
At 208 places, the spark of each adjustment in multiple cylinders of motor can be compared.Then controller can determine (and only one) cylinder in multiple cylinders of motor with maximum spark retardation.That is, the cylinder of the spark timing with maximum delay can be determined.Therefore, be have the highest tendency to detonate cylinder and also can be called as in this article " cylinder of worst case ".At 210 places, the expection that this program comprises the delivery temperature that estimation (or prediction) is associated with the maximum spark retardation of the cylinder of worst case is risen.
At 212 places, the estimation comprised based on the delivery temperature in the cylinder of worst case of this program is risen and is determined the enrichment of fueling, and this enrichment will maintain delivery temperature under threshold temperature.Threshold temperature can based on the limiting design value of engine components.Such as, threshold temperature can one or more based in exhaust valve temperature, turbine inlet temperature and exhaust catalyst temperature.Therefore, the enrichment maintained required for delivery temperature can increase with the increase of the maximum spark retardation in the cylinder of worst case.
At 214 places, this program comprises based on the enrichment determined (this enrichment is based on the spark governor of the cylinder of worst case) to each fueling in multiple cylinders of motor.Particularly, the fueling of whole cylinder can be adjusted and each in multiple cylinder can based on maximum spark retardation by enrichment equably similarly.Therefore, although each cylinder can have the spark of different adjustment, each cylinder can use identical enrichment to carry out fueling.
Spark adjustment and fuel adjustment can organize perform upper with group base (as in V-motor).Such as, multiple cylinder as discussed above can be coupled to the first cluster engine and motor may further include the second cluster engine.Wherein, the first cluster engine it is expected to pinking, and do not anticipate pinking on the second cluster engine.Then controller can based on each in multiple cylinders of the maximum spark retardation enrichment first group of the cylinder of the worst case of the first cluster engine and to the cylinder fueling of the second cluster engine to maintain the exhaust air-fuel ratio of second group at stoichiometric proportion place or near stoichiometric proportion, or any reference that air-fuel ratio (Maximum Torque (LBT) as the pedal performance-the rarest of Full-open) is ordered.Therefore, the delivery temperature of the first cluster engine can be maintained under the threshold temperature of the delivery temperature not relying on the second cluster engine.
In another example, wherein pinking also can be expected in the second set, and controller also can postpone spark timing based in each in multiple cylinders of the second cluster engine of the independent self adaption knock control value of each in multiple engine cylinder from MBT.Then the maximum spark retardation that can determine based on the worst case of second group (cylinder) in multiple cylinders of second group of controller and each in multiple cylinders of enrichment second group.Illustrate that example adjusts with reference to figure 3.
Will be appreciated that, although the program of Fig. 2 illustrates that whole cylinders of motor receive fuel equably based on the spark governor of the cylinder of worst case, but in further embodiments, the fuel trimmer of whole cylinders of cluster engine can be adjusted according to the spark governor of the cylinder of worst case.Such as, the cylinder with maximum spark retardation can use the spark governor based on given cylinder and correspondence based on delivery temperature estimates that the enrichment risen carrys out enrichment the delivery temperature of given cluster engine to be maintained under threshold temperature.Meanwhile, the fueling of the residue cylinder in multiple cylinders of cluster engine can based on the fueling of in multiple cylinder (this cylinder has maximum spark retardation) to maintain exhaust air-fuel ratio at stoichiometric proportion place or near stoichiometric proportion.
In this way, the knock control between cylinder and cylinder can realize and adjust via the fuel between the group of the overall situation and group the delivery temperature of cluster engine being maintained in limit value via spark adjustment.
In one example, the method that engine knock controls comprises the self adaption knock control value based on respective cylinder and differently postpones the spark ignition timing of multiple engine cylinder; And based on have in multiple cylinder maximum spark retardation an only cylinder ignition timing and adjust to each in multiple cylinder fuel spray so that delivery temperature is maintained under threshold temperature.Fuel adjustment can comprise the enrichment of each adjusted equably in multiple cylinder, enrichment and maximum spark retardation proportional and do not rely on the spark lag remaining cylinder.At this, multiple engine cylinder can be included on the first cluster engine.Adjustment fuel sprays the fuel of each comprised in multiple engine cylinders of adjustment first cluster engine to maintain delivery temperature and sprays the delivery temperature of the first cluster engine to be maintained under threshold temperature.Therefore, the delivery temperature of the first cluster engine can be maintained under the threshold temperature of the delivery temperature not relying on the second different cluster engine.Threshold temperature can one or more based in exhaust valve temperature, turbine inlet temperature and exhaust catalyst temperature.Therefore, threshold temperature can be adjusted in the limiting design value of one or more engine components.Postpone spark ignition timing based on self adaption knock control value can be included in first cylinder with higher tendency to detonate and postpone spark ignition timing with higher spark lag degree, and in second cylinder with lower tendency to detonate with lower spark lag degree to postpone spark ignition timing.Adjustment fuel spray can comprise use based on the enrichment of the higher spark lag degree in the first cylinder come in enrichment first and second cylinder each.
In another example, engine system comprises first group of cylinder on the first cluster engine, second group of cylinder on the second cluster engine, is couple to the fuel injector of each engine cylinder and is couple to the spark plug of each engine cylinder.Engine system comprises the controller with the computer-readable instruction be stored on non-transitory storage further, and described instruction is for following operation: occur based on the pinking in respective cylinder and learn the self adaption knock control value of the cylinder spark timing on cylinder and casing base; The spark timing differently postponed in each engine cylinder based on respective self adaption knock value; Estimate the exhaust gas temperature change be associated with the spark in each cylinder adjustment; Determine first cylinder the first cluster engine in first group of cylinder with maximum spark retardation; Determine second cylinder the second cluster engine in second group of cylinder with maximum spark retardation; And based on the first cylinder spark lag and to each cylinder fueling in first group of cylinder, and based on the second cylinder spark lag and to each cylinder fueling of second group of cylinder so that the delivery temperature in each cluster engine is maintained under threshold temperature.
At this, comprise each cylinder of enrichment first group equably based on the spark lag of the first cylinder to each cylinder fueling of first group, and comprise each cylinder of enrichment second group based on the spark lag of the second cylinder to each cylinder fueling of second group.Threshold temperature can based on catalyst temperature, and the feedforward possibility countercylinder spark timing that self adaption knock control value can comprise based on pinking in cylinder adjusts.
Now go to Fig. 3, the adjustment of example spark and the fuel adjustment of knock control are shown for first group of cylinder (cylinder 1 to 4) of the first cluster engine (group _ 1) and second group of cylinder (cylinder 1 to 4) of the second cluster engine (group _ 2).Spark adjustment and fuel adjustment perform in group with group base, and the delivery temperature organized can be maintained in part design limit value.Particularly, at plotted curve 302 place, mapping graph 300 illustrates that cylinder spark adjusts, and cylinder fuel adjustment is shown at plotted curve 304 place and the concrete exhaust temperature profile organized is shown at plotted curve 306 place.
Plotted curve 302 illustrates the spark lag amount that each cylinder of the first cluster engine and the second cluster engine is determined.As shown, each cylinder can use different spark lag amounts to operate.The spark lag of each cylinder can based on drive learn in circulation and the independent cylinder self adaption knock value retrieved from the storage of controller and being determined.Cylinder _ 2 in the first cluster engine maximum spark retardation that can be configured in use first group operates and can be called as " cylinder of worst case " (as via indicated by asterisk) of group _ 1.Similarly, cylinder _ 3 of the second cluster engine maximum spark retardation that can be configured in use second group operates and can be called as " cylinder of worst case " (also as via indicated by asterisk) of group _ 2.
Plotted curve 304 illustrates the fueling that each cylinder in the first cluster engine and the second cluster engine is determined.Be maintained in threshold value 305 in order to ensure the delivery temperature of each group (plotted curve 306), the enrichment that whole cylinders of first group use the spark lag based on cylinder _ 2 and adjust carrys out enrichment, and the enrichment that whole cylinders of second group use the spark lag based on cylinder _ 3 and adjust carrys out enrichment.Therefore, although cylinder uses the spark governor of change to operate, the cylinder of given group uses conventional fuel trimmer to operate, and this fuel trimmer is based on the fuel trimmer of the cylinder of the worst case of given group.As shown in plotted curve 306, this allows knock control and also maintains delivery temperature in the limit value of temperature-sensitive engine components.
In this way, the pinking that the spark adjustment of concrete cylinder can be implemented to solve in independent cylinder occurs.Then, the delivery temperature that the fuel adjustment specifically organized can be implemented with control group.By based on solve the temperature that is associated with the cylinder with maximum knock control spark lag amount rise required for fueling and equably to the whole cylinder fuelings organized (such as, enrichment), sludge water treatment (over-temperature) condition can be lowered.Therefore, this extends the life-span of engine components and improves engine performance.In addition, the fuel adjustment of concrete group allows to improve fuel economy when not deteriorated knock control.
